Custom image builds for some open source projects. For example, it can be used for rebuilding an image with a current golang runtime or a new base image. Other kind of simple patching are also possible.
First you may change the REGISTRY variable in common.mk to define the registry used to push your custom images.
Then adjust or add custom builds in *.make files.
To run all changed or new custom builds just run
make allIt will only build images whose .make file is newer than its marker file markers/*.done.
To develop a custom build, create another .make file containing how to download the sources, building the container image
and how to push it to your registry.
Building the container image is performed using docker in docker typically.
You must also create a corresponding marker file in the subdirectory markers.
For example for a custom build named my-custom-build.v1.2.3.make run these touch commands
# create an empty marker file
touch markers/my-custom-build.v1.2.3.done
# ensure that make file has newer timestamp
touch my-custom-build.v1.2.3.makeIt is expected to have a target all to perform all necessary steps.
To test a target for correct execution, run
make -f my-custom-build.v1.2.3.make <target>Here target can be all or any target defined in this makefile.
